Background Crocodilians have dominated predatory niches at the water-land interface for over 85 million years. - Over time, the most "divergent lines" of crocodiles died off, leaving the squat-bodied, short … These differences are often assumed to reflect anatomical specialization related to feeding and niche occupation, but quantified data are scant. Of the many species on earth today that can trace their ancestry back to prehistoric times, evolution has touched crocodiles perhaps least. https://prezi.com/yz7xwi1ffbar/evolution-portfolio-saltwater-crocodile These massive creatures are known by a slew of names, including sea crocodile, Indo-Pacific crocodile, saltie, marine crocodile, and estuarine crocodile.They also have an incredibly wide distribution, as they live in regions from India and Asia, to Australia. It’s true that crocodiles haven’t changed much over millions of years, but that’s because they’re so successful at exploiting a niche that hasn’t changed much either. Crocodile - Crocodile - Natural history: The young crocodile emerges from the egg with a length of 20–30 cm (8–12 inches). Saltwater crocodiles are not the only animals that have adapted to a semi-aquatic existence; animals from a variety of lineages exhibit similar adaptations. Saltwater crocodiles are the largest living reptiles on earth. - 65 million years ago, many crocodile species survived the asteroid that wiped out the dinosaur species, probably because of their freshwater habitats, as opposed to saltwater habitats. At first it remains with its siblings concealed at the edge of its water habitat in order to avoid various predators. They found the creatures have an unusually slow rate of genetic evolution Birds and crocodilians shared a common ancestor 240 million years ago But while birds evolved quickly, crocodile… The order Crocodilia includes giants like the saltwater crocodile, but it also contains smaller species that average under 5 feet, like Cuvier’s dwarf caiman. Along with pterosaurs and dinosaurs, crocodiles were an offshoot of the archosaurs, the "ruling lizards" of the early-to-middle Triassic period of the Mesozoic Era.This epoch in history began about 251 million years ago and ended 65 million years ago. For example, just as crocodiles have webbed feet that help them to swim, animals as diverse as beavers, ducks and frogs also possess and use webbed feet. This Pokémon is known as the Bully of the Sands. So evolution cannot stop. While terribly aggressive, Krookodile also has the patience to stay hidden under sand for days, lying in wait for prey. At their largest, these saltwater crocodiles can grow up to 23 feet long! Like their ancestors, living species show substantial variation in their jaw proportions, dental form and body size. Principal among these are fishes and birds, but … The 23 species of crocodilians in the world today enjoy a global distribution, limited only by habitat loss, hunting, and cold weather. Earth’s largest living crocodilian—and, some say, the animal most likely to eat a human—is the
